Reinforced concrete wells - their features and device

If you are engaged in arranging a country house or giving in the village, where there is no centralized water supply, the device in the area of ​​the well is an excellent solution in this situation. Many believe that this is a very difficult and costly job, however, precast concrete wells can be completed without being a specialist, without the use of special equipment.

And then we look at how this is done.

Preparatory work

Before making a water well from precast concrete, it is necessary to do some preparatory work. Moreover, the most important thing in this case is to correctly determine the place for the future source of water supply..

To find the best place, you should perform a survey to determine the presence of the aquifer and the depth of its occurrence. In addition, at this stage, you can determine the quality and quantity of water.

However, these procedures require additional costs, since the price of such services of specialists is quite high. Therefore, you can save money by getting all the information from your neighbors.

Most likely, the conditions on your site do not differ much from those on neighboring sites. The same goes for water quality.

It should be said that the decisive moment when choosing a place is not only the depth of the location of the aquifer. According to the existing GOST, the source should be located at a distance of at least 30 m from toilets, manure storage areas, sheds and other similar structures. In addition, it is not recommended to perform wells near rivers or on the slope of ravines.

Once you have decided on the location for the water source, you can begin to make a water well from precast concrete.

Design features

So, constructions can be arranged in two ways:

• Monolithic concrete.
• Precast concrete well, made of ready-made rings.

Monolithic structures are built of concrete, which is prepared on site. However, this process is very time consuming and slow. Run this well yourself is unlikely to succeed.

It is much more convenient, easier, faster and more economical to build water wells from precast concrete. The walls of this design are strong and durable. In addition, they are well protected drinking water from various contaminants.

Tip! To isolate the columns from surface water and other pollutants, the joints of the rings should be oiled with a solution of cement and liquid glass.

The structure of the well of concrete rings

Before proceeding with the construction, consider the main elements of reinforced concrete wells:

• Ogolovok - the upper part of the structure, which does not allow storm water into the mine, and also protects the well from freezing in the winter. The heads can be both round and rectangular.
• The main trunk - the average, the main part of the structure. Most often has a round shape.
• Water intake - part of the structure, located in the water. Water intake is used for storing and accumulating water. The depth of this part depends on the volume of daily water consumption.
• The buzzer is the lower part of the column in which water is accumulated (used only in some specific cases).

Principle of construction

Round wells from precast concrete are mounted by bottoming method.

Construction is carried out in the following order:

• First of all, a mine is dug up by a depth of one and a half rings and a diameter of 20 centimeters larger than the diameter of the ring.
• In the lower ring, holes are made in staggered order (or rings with holes are purchased in advance).
• Then the bottom deepens, as a result of which the rings under their own weight fall down, while at the same time, new rings are placed on top of the vacant space.
• When the mine reaches the required depth, the bottom is filled with crushed stone of fine fraction, which serves as a filter for the well.

Tip! Land can be raised up with a tub or bucket and rope. To simplify lifting, a tripod with a block is installed above the well.

Installation of concrete rings

More detailed instructions for making a well are as follows:

• First of all, the lower ring, the diameter of which should slightly exceed the diameter of the lower rings, is lowered into the dug trench. If the soil is hard rock, then a metal knife is attached to the edge of the ring.
• Next, the next ring is installed, and when the ground is deepened, the structure gradually descends. To seal the columns, tarred rope or other material is placed between the rings. This carefully checks the verticality of each installed element.
• Thus, the installation of all other rings, to the required depth.
• Then, after the second ring, the internal joints are cleaned.
• At the bottom, as mentioned above, the well filter is laid down, after which dirty water is removed.
• After completing the wellbore, the external seams should be filled with the solution.
• Then it is necessary to increase the strength of the structure by fastening the rings with brackets, which must first be coated with oil paint.

Tip! When installing the rings sometimes they are built up, as a result of which they fall unevenly. To avoid this problem, one should weld a metal bar to the bulging reinforcement of the lower ring and fasten all the concrete rings together.

The last step in arranging the well is to install the tent with your own hands, which covers the well by 30 to 40 cm. The walls can be made of stone, timber, concrete or brick. The design also needs to be equipped with a hinged lid.

It should be borne in mind that the hatch must be waterproof and durable. In addition, it is necessary to provide hinges so that the cover can be locked with a lock. Thanks to such a well roof, it will not get dust, debris, dirt, as well as climb insects and rodents.

After construction, the water must be pumped out several times. In addition, during the first week you can only use water for technical purposes.

Tip! Before using water for drinking, it is advisable to perform its chemical and bacteriological analysis, which will make it possible to more accurately select a filtration system.

Conclusion

Having dealt with the technology of construction of such structures, it is quite possible to cope with the work independently, without the help of specialists. The most important thing is that reinforced concrete wells are made according to GOST, in compliance with all requirements, otherwise the construction will be a waste of time, money and effort.
